Is the speed of human vision the same as the speed of light, and why can you see the stars when you

Of course, the speed of human vision is not comparable to the speed of light, and the reason why we can see the stars when we look up is actually that "photons" play a role in transmission. We all know that since the great physicist Albert Einstein in the last century, and his special theory of relativity, the two major systems of general relativity have been born;

Not only has the world of physics been turned upside down, the greatest talent of all time; Moreover, it also made us realize for the first time what a magical power the "speed of light" is. It is said that when the speed of matter really reaches the speed of light, not only can decay be transformed into magic, but even "traveling through time and space" is no longer a fantasy.

It's amazing how fast light is so incredible. However, with our eyes, we can see the presence of light beams, and we can also capture various light and dark changes of light. Does this mean that the speed of human vision is faster than the speed of light?

Of course not, this question is actually a complete "false proposition".

Why? Because human beings use the naked eye to perceive and perceive everything that is happening around them, the medium that plays the role of "transmitting information" is the photon. It is the refraction of light, which is fed back to the naked eye, and then our naked eye transmits it to the mind through the nerve center, forming a specific picture;

In other words, the eye is just a "receiver". There is no such thing as speed in the strict sense of the word. Just like when we look at the vast sea of stars in the night sky every night, it is also the "refraction of light" that comes into play, not that we really have "clairvoyance" and can see the planet dozens of light-years away.

Of course, most of the stars that appear in the sky at night are not far away. According to data provided by NASA in 2018, 98.9 percent of the stars came from near the edge of the solar system.

Planets that are too far beyond the solar system, if they are not particularly bright, then we will definitely not be able to detect them with the naked eye.

The human eye? The human eye does not emit light, and the person can see the object because the light reflected or emitted by the object enters the human eye. Looking up and seeing the stars is the light they emitted a long time ago, traveling a certain distance to reach the earth and entering the human eye.

There is no comparative value. It is the photons that are doing the transfer. We can see the presence of light beams, and we can also capture the various changes of light.

It's not the same. Because the human eye has no speed, it can only passively receive light. The reason why you can see the stars when you look up is because you can receive light from the stars when you look up.

The speed is different, and he can see the stars because the light emitted by the stars has traveled many light years.

The human eye can only passively receive light, and there is no speed, so the speed is not the same. Because the human eye can receive the light of the outside world, it can see stars hundreds of light-years away when you look up.

The speed of light can be very fast, reaching 300,000 kilometers per second, but what the human eye sees is actually the light emitted by the light source itself.

The speed of the eye is indeed faster than the speed of light, because the speed of the eye is super light, and this super beam of light can see stars hundreds of light-years away.

The reason why the eye sees things in the brain is because light enters our eyes, which eventually causes a response from the optic nerve, and this impulse is transmitted to the brain. An object can be seen, mainly because it can emit light.

Generally speaking, there is an essential difference between the speed of human vision and the speed of light, and most of the time, because of people's slow reaction, it is impossible to keep up with the speed of people's eyesTheoretically, the speed of light is fundamentally different because of this, but the reason why we can see stars other than the New Year is because the light itself has been flying in the universe for a long time, so it is said that the information of hundreds of millions of years ago is transmitted, and then people are affected by the scene of seeing the stars of light years away, in general, because of the following reasons. <>

1. Generally speaking, it is difficult for human body functions to adapt to the speed of light, so because of this, the speed of human vision cannot be compared with the speed of light. In fact, for us, it is also difficult for human body functions to adapt to light, speed in some aspects, the limitations of the human body cause people to be unable to make their own sunlight speed keep up with the speed of light, so in some sense, this is the shortcoming of the human body, so it is incomparable with the speed of attack. <>

2. Most of the time, the reason why we see stars beyond light years is also because people have infinite vision, so they can see the light emitted by stars light years away. In fact, theoretically speaking, if the stars that are a year away do emit light, then at this time they will also pass through the long space of the universe and enter the human eye, so they can also be perceived by people, and in some ways, people can indeed see the stars that are light years away, and they also change differently with different locations. <>

3. Most of the time, it takes a certain amount of time for light itself to propagate in the universe, so this is because the distance is relatively far, and there may be a distance of light years, so you can also see the previous stars. In fact, it takes a certain amount of time for us to travel light in the rain, and because of this, if we are far away in the basin, then we may also be able to see the light emitted by our own year-old stars at this time, so in some sense, we can indeed see these stars, but these stars do not seem to exist anymore.

In fact, most of the time because of the limitations of the human body, the speed of human vision is unable to keep up with the speed of light, on the other hand, the reason why we can see the distance of light is also because the speed of light in the universe is limited, so it is because of this that the information we see comes from the light emitted by things a long time ago.

It's not the same. Because the eye directly receives light passively, there is no speed, so it is not the same as the speed of light. Because the light of a star light years away travels into the human eye, it can be seen.

The speed of human vision is not the same as the speed of light. Because once the light is emitted, it travels in a straight line until it disappears, and the reason why you can see a star light years away means that the star reached the Earth millions of light years ago.

It's not the same, because the speed of light is faster, because the stars are very big, so they are far apart, and we can see them as well.

When you wake up, you can see stars a few light-years away, does this mean that the eye is faster than light?

Not greater than the speed of light, close to the speed of light. With the help of astronomical telescopes, the human eye can capture stars hundreds of light-years away, with the help of many optical principles.

Because the eye passively receives light, there is no speed, not greater than the speed of light. Because the light of the stars enters the human eye, humans can see the stars.

It is impossible for the human eye to be greater than the speed of light. The reason why you can see a star hundreds of light-years away is because the light emitted by that star has taken hundreds of years for your eyes to see, and in fact you see what the star looked like hundreds of years ago.

What is the speed of the human eye, and does it mean the reaction speed of the captured light? In any case, the speed of light is the fastest known speed, and you can see stars hundreds of light-years away because light travels hundreds of years before it reaches your eyes.

I think the human eye does
